Fig. 2 is a section taken along the line 22 in 'Fig' 1. Fig. ,3 is an enlarged .view of theinner face of the crank. Fig. 4 is a top plan view of the crank and ban e and indicating by the dotted lines the second position of the handle; Fig. 5 is a plan view of the track. I i

Referring to the accompanying drawing it'willbefseen that this door 10 is mounted upona freight car 11' and is held in a verticalposition by means of the guide bar-s12 and 13 and is mounted upon a-track 14. The

The gear wheel is positioned out of alinement with the rollers 15 and enga es the teeth formed upon a flange 18 carrie by the track 14:. The ear wheel is mounted upon an axle 19 which has its inner end formed into a head 20 which is mounted in a socket 21 and has a crank 22. mounted upon its outer end. A handle 23 provided with grooves 24: adjacenteaeh end is mounted in an opening formed in the crank 22 and is held in place by means of the heads 25. A sprintg1 arm 25 is mounted upon the inner faceof e crank 22 and is adapted to engage one of the grooves 2 .1. to hold thehandle in either the position shown in Fig. 2 Oigtilfi position shown; in Fig. 1;.
